<p>Late IPA passes are simple IPA passes executed after
the regular passes.  In WHOPR mode the passes are executed after
partitioning and thus see just parts of the compiled unit.

<ul class="itemize mark-bullet">
<li>Materialize all clones

<p>Once all functions from compilation unit are in memory, produce all clones
and update all calls.  It is located in <samp class="file">ipa.cc</samp> and is described by
<code class="code">pass_materialize_all_clones</code>.
</p>
</li><li>IPA points-to analysis

<p>Points-to analysis; this is the same as the points-to-analysis pass
run with the small IPA passes (see <a class="pxref" href="Small-IPA-passes.html">Small IPA passes</a>).
</p>
</li><li>OpenMP simd clone

<p>This is the OpenMP constructs&rsquo; SIMD clone pass.  It creates the appropriate
SIMD clones for functions tagged as elemental SIMD functions.
It is located in <samp class="file">omp-simd-clone.cc</samp> and is described by
<code class="code">pass_omp_simd_clone</code>.
